arena Swim of the Week: Rylee Erisman Becomes Fastest 15-Year-Old American Ever In 100 Free

Swim of the Week is brought to you by arena, a SwimSwam partner.

Disclaimer: Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The Swim of the Week is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.

Rylee Erisman entered rarefied air on Friday morning at the Speedo Sectionals in Ocala, becoming the fastest 15-year-old American female ever in the 100 freestyle and cracking the top 10 globally all-time.

Erisman blasted a time of 54.34, overtaking Gretchen Walsh (54.38) as the fastest U.S. 15-year-old girl in the event.

The performance marked a monstrous best time for Erisman, who had gone a PB of 55.09 just two months ago at the NCSA Spring Championships.

Split Comparison

Erisman, March 2024 Erisman, May 2024
26.86 26.12
55.09 (28.23) 54.34 (28.22)

The most incredible thing about Erisman’s swim on Friday is that she only turned 15 recently—her previous best from NCSAs was done when she was still 14, as it moved her into #3 all-time in the girls’ 13-14 age group behind only Missy Franklin (54.03) and Lia Neal (55.00).

In addition to taking hold of the distinction as America’s fastest-ever 15-year-old, Erisman also sits 7th globally in the event historically, according to USA Swimming’s database.

She followed up her 100 free prelim on Friday by clocking 1:01.28 in the 100 back, with her PB standing at 1:00.58 from NCSAs.
